Wondering if anybody can help me get rid of a transmission noise. That I keep getting on my MAX IV 25Kohler. It only seems to happen when im going down a hill and I pull back on the stearing. When I do this a nocking/clicking noise happens.
At first I tought it was my chains.....but me and a friend really checked it well and the noise seems to be comming from the transmission.
Does anybody have any ideas? |

MrMonday, I'm going to guess that your noise is tranny chatter (the bands not fully engaged and bouncing on the drums just a little). The friction modifier that is currently used, eliminates this under most circumstances, but I can see it might not when going downhill.
To rule tranny chatter in or out, try going downhill as you were doing when you first noticed it. If you get the noise, put a little more pressure on the steering laterals to see if it quits. Try more or less pressure on both sticks; if the noise goes away with either more or less pressure, it is tranny chatter and will do no harm. |

Fred, On the Max IV what is the correct amount of steering lateral movement from fully forward to full brake while in forward? |

Jerry, From 5.5 inches to about 11 inches. I usually adjust for 7 inches between the center of the laterals with one all the way forward and one all the way back. Important to have internal neutral (not enough travel will eliminate neutral) and not to hit the dash or the seat (too much travel).
Actually the travel is the same on all models any make machine that uses a T-20. |

Ok, I drove one a couple of weeks ago and thought there was way too much travel. It seemed like I had to pull back a very long way to apply the brake on either side. So if you adjust for seven inches between the two does that mean 3.5 inches of travel before neutral and when does the brake begin to start working? |

Hi Fred,
Your right on with your answer....thats excalty what it is "tranny chatter". The noise is kind of annoying and was wondering if theres a way I can fix this?
What is the friction modifier? Im not sure what that is.....could u describe this for me.
thank u very much... |

the friction modifier you ask about is called "GM limited slip axle lubricant additive". it is a specially compounded formulation which when used in limited slip rear axles tends to modify excess clutch plate friction and facilitates the applying and releasing of clutch plates. it comes in a 4 fl. oz. plastic bottle. some recomend only using 2 oz. of the product in a t-20 tranny. (i put 4.oz in mine) |

Jerry, I'm just guessing here. I'm going to say there is an inch and a quarter between partially engaged and fully engaged (either brake or power) and probably two and a half inches of neutral (the more total travel, the more neutral). The travel has no effect on performance unless the bands are prevented from becoming fully engaged.
MrMonday, Terry H gave you the scoop on the friction modifier. RI started using it around 2000 and uses 4 oz. with Type F ATF. Your machine would have had it in it when it was new. If your ATF was changed and the modifier not replaced, you would get reduced effect from the old stuff for a while, but you should have noise every time you engage the bands, not just when going downhill. I notice tranny chatter most when I am turning. I slip steer and my tranny really talks to me (I don't use the modifier in the 1995 Max IV that I use).
Whether to use the modifier is another subject. |

Jerry, the travel on my Max IV was about 11 inches. I adjusted it down to about 6 inches. I also loosened the spring tension on the laterals. That made the machine a bunch easier to drive and feel alot more responsive. After riding at Haspin last month my fore arms felt like Popeye's from fighting the spring on the laterals. |

Thanks alot everyone....
Is there a way to know exaclty what the spring tension should be set at or is there any manuals or video on how to set the steering?
Even any video on Max assembly? |

liflod, I test drove one for about 15 minutes and I had the same thing... burning forearms. I had to pull the sticks back into my body to get it to brake and it seems like there was a foot of travel. This is what got me wondering what the travel is and could also be why the guy was selling it. |

Jerry, I drove a T20 in a maxII that was out to lunch like you describe. And have driven one that was in good shape all around. I don't think you'll have any complaints about your new max's steering if it's all working well. It's not as physically effortless to steer as an argo, but you'll be busy enjoying what the T20 offers. |
